Hi, I’ve had my gecko for roughly 8 years. When we first had her we were advised by the pet shop that the red heat lamp was the way to go however upon research I’ve realised this is not a good option. I have bought a UVB tube today as an addition and she has vinyl flooring as substrate. 4 hides in total including her shedding hide. I have ordered a digital thermometer as another precaution however I do have a hygrometer and two thermometers already In the tank, however these are not digital. Looking for an alternative to the red heat lamp; a basking lamp would work however turning this off in the night would mean the temperature would drop too much, am I able to put a heat mat in a wooden vivarium? Any advice would be great
